Call two arms equally strong if the heaviest weights they each are able to lift are equal. Given a sequence of integers as an array, determine whether it is possible to obtain a strictly increasing sequence by removing no more than one element from the array. Refactoring covers not only lines of code into a function, but of data objects into different structures.
